Application filed December 28, 1921. Serial No. 525,528.

To all whom t may concern.'

Be it known that I, ADAM FunnsrnNnEnc,

a citizen of the Dominion of Canada, residing at lVatson, in the countyof Humboldt and Province of Saskatchewan, have invented certain new anduseful Improvements in Self-@peiling Garage Doors, of which thefollowing is a specification.

The present invention relates to a self# opening garage door. Theprincipal object of the invention is to provide a device in combinationwith garage doors, whereby the doors may be automatically opened andclosed by an automobile entering or leav ing the garage without thenecessity of the driver moving from his seat.

Vith this and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawingsand pointed out in the claim hereunto appended.

Figure 1 is a front plan view illustra-ting my present inventionembodied in conjunction with a garage, the device being in operation.

Figure 2 is a side elevation, further illustrating the construction ofmy invention.

Figure 3 is a perspective view of one of the hinge members used inconjunction with the runway mechanism.

Jferring to the drawings, like numerals designate like parts in thevarious drawings.

rlhe numeral 4 indicates the` garage, 5 and G the sliding doors, 7 and Sthe runways and 9 and 10 the members for guiding the runways. 11 and 12indicate the runway hinge members.

As an automobile enters the garage, the

bers 11 and the same press the adjustable runways 7 and 8 downward. Thisdownward movement pulls the flexible cable 13 downwardly and theflexible cable being connected to the doors 5 and 6 at' 1-1 and 15, pullthe doors open as indicated diagrammatically in Figure 1.

When the weight is removed from the runways the doors automaticallygravitate to closed position due to the inclination of the front wheelsbear on the front hinged memtracks 18, The springs 16 and 17 tend tocushion the closing movement of the doors and to prevent the cable 13from becomingslack. Obviously when the doors move from open to closedposition the runways will be raised and repositioned for subsequentactuation.

Then an automobile leaves the garage. the action is similar. The runwayhinges, more clearly indicated in Figure 3, are positioned as indicateddiagrammatically in Figure 2 and assume the position indicated by dottedlines when the automobile is entering or leaving the garage. The slidingdoors G and Y are slidably mounted on the track 18, the doors being hungfrom bracket 19 which have the rollers 20 positioned to bear on thetrack 18, also, the cable 13 is preferably housed in a casing 21, thecable passing over the pulleys 22 which serve to keep the same in properposition. The runways 7 and 8 need not be of any particularconstruction, as all that is required is a fiat running surface for thewheels of the automobile.

lhile I have illustrated and described the preferred form ofconstruction of my invention, this is capable of variation andmodification without departing` from the spiritof the invention. I,therefore, do not wish to be restricted to the precise details ofconstruction specified, but desire lo avail myself of such variationsand modifications as come within the scope of the appended claim.

From the foregoing, it is thought that the construction of my inventionwill be clearly understood and therefore, a more extended explanationhas been omitted.

lVhat I claim as new is:

In combination with a doorway a pair of sliding doors therefor, saiddoors hung for movement along the opposite ends of a track which isinclined downwardly from either' end toward the center, a pair ofwheelways extending under and to either side of said doorway each ofsaid wheelways having` a depressible member of T shape in cross-sec'-tion. a flexible member provided at either end with a resilient elementone of said elcv ments being attached to each door near the upper7 innercorner thereof, said flexible member being trained over pulleys arrangedin vertical housings at either side ofeaid doorway and extends undersaid wlieelways for actuating the doors to open position when weight isplaced .on the depressilile members, the inclination of said trackCansingthe doors to close hy graif'ity when the 'wel ght is removed.
